const MAX_NODES: u32 = 16384;Expand description
Maximum number of nodes visited during a single traversal.
Prevents excessive execution time on graphs with high fan-out. Set to the 16384 cap recommended by security analysis. Above HarfBuzz’s limit of 2048 (https://github.com/harfbuzz/harfbuzz/blob/9f2f03173b7fee860cc00d999857d09fa4a362e2/src/hb-limits.hh#L96) since we have seen some glyphs (Noto Emoji Color flags) use about ~6700 in practice.
